The first watch, the Breguet no. 4039, was originally sold to the Duke of Berwick on September 1825, and went for a final auction price of 70,000 Swiss francs at Christie’s. The second timepiece that Breguet’s CEO acquired may be even more exceptional. It is Abraham-Louis Breguet’s very first watch with a four-minute tourbillon, and only the third tourbillon watch that the master watchmaker ever made. These two limited edition pieces return now to the hold of its manufacturer.
